Glaze Formulation & Scratch Resistance
Manufacturers must utilize a specialized high-temperature glaze (typically fired at 1200°C or higher) to ensure the pigment fuses perfectly with the ceramic body. This prevents the color from fading or yellowing over time and provides a smooth, scratch-resistant surface.
Color Consistency Across Components
Achieving a uniform hue across different components (like the tank, lid, and bowl) is critical. Advanced factories use digital color calibration and strict quality control measures to eliminate batch-to-batch color variations
Durability Testing
Colored ceramics must pass rigorous thermal shock testing to ensure the pigmented glaze does not crack or craze under extreme temperature changes.
